on the rampage. the gunman was later found dead in the school building in an apparent suicide. u.s. media say he was armed with at least two guns and was wearing a bulletproof vest. police are interviewing the gunman's family members as they try to determine his motive. president obama spoke to the nation. >> we've endured too many of these tragedies in the past few years. and each time i learn the news, i react not as a president but as anybody else would as a parent. and that was especially true today. the majority of those who died today were children. beautiful little kids between the ages of 5 and 10 years old.
